The results of photoluminescence (PL) imaging performed with a laser line scan in a prototype setup are presented in this work. Here we show the PL images with the photovoltaic cell positioned at different distances from the laser line source, therefore with the beam at different intensities and line characteristics.
This study is motivated by the time demanding process of acquiring luminescence images for accurate PV inspections in the field, usually made with electroluminescence imaging. The PL imaging induced by a laser line has the potential to be compact enough to be portable and carried out by drones for field inspections.
